@he 'form 0i" fiu- '10 is a, having: mlfyzontu b1 verlie! brunch ll ing in the d in Fig. l,

ed as shown at 15.

thrad L1 an hose member i9 threads 15, the coupl 0 Ilxny Ml,

0 the horizontal brunch i Justed up or down the cap 22 to Wholly shut off the flow of Water into the groove 28 and Consequentl)rv the flow of spray through the opening 2.3. When itis desired to change the character of the spray the cap 22 may be given a conm plete revolution or several revolutions if desired so that the. area of the opening 3U will be largely increased. It is thus poser ble to regulate the opening 30 or to regu lte the efeetive area of the 'port 29 where it opens into the groove 28.

In the form ol' the invention illustrated in Fig. 2 a T-shapefl body member 5l has horizontal branmee provided with internal threads into which pipe members 53 are threaded. A vertical branch .'34 of the body member 5l has :in external thread 55 formed thereon and cap 5G is rigidly and permanently' secured on the thread 5.3. Threaded :inside the cap 56 a thimble 57, this thimble having an external thread 58-by which it may be adjusted up or down inthe cap 56, The cap is threaded at 59 and a ping (Si) is threaded therein. this plug having' a central opening 6l through which the spray iinally emerges. ,A square recess 6:2 or a screw driver slot provided in the top of the thimbie 57 in line with the opening G1 so that the thimble can he ail-- in the cap 56 without the necessity for renewing the eap 5&6 from the body member 5i or removing the plug 65) from the body member 51. Spiral groom 63 are eut in the inner surface of the hotly member 56 these grooves tapering upwardly and having their greatest area at the lower enel. They are of such length that they communicate with a cavity Y65 above'the thimble 5?' fand below the plug 60 in the wall of the tliirnble, theee ports serving to allow water to pase therethrough from the interior of the body member 51 to the groove 63.

The method of operation of the invention is as follows: The pipes 53, the body .member 51 and the connecting parte are assembled in place in the ground apln'oximately as shown in the .lrawiuge ll'lienever if desired to regulate the total quantity of Water passing from the port 10 into the groove (t3 this can, lle done by :i partial turn of the tliimlle 5T. this partial revolution turning the ixiemlier ai in smell a poeition as to Wholly or parially .Sfmt oil the How ol' water to the groove $53. llhen it i@ le sired to materially harige the lim-,nears of the spray il; can he duur by a, similar more ment of the tliiiulle Si it` being poseiiie tu turn the thimlfle Si? through -wral revo luifionsS illierfflfj gi'ratlj.' inrwaemg the sii/Je of the opening;

In testinuafy whereof, l have hereunto set my hand at Los Augeee, California, this 13th day of May, 1915.
